Compressed air spraying

  • Spraying pressure 5 - 6 bar
  • Nozzle size 1,5 - 2 mm
  • Adjust to spraying viscosity (appr. 60 s DIN 4 mm) adding appr. 6 % Deripox-Hydro-Verdünnung (two component products: after mixing)

Electrostatic application

  • Application is possible, provided the equipment is suitable for water based materials


  • Can not be applied as delivered

Other methods

  • Roller and brush application for repair work is possible


  • Max. 10% Deripox-Hydro-Verdünnung
